Fast, Reliable Heat Pump & Mini Split Across Hollywood
Heat pump and mini split installation in Hollywood typically runs $3,500–$7,500 for a full system, with same-day repair calls available for compressor lockouts and refrigerant leaks. We serve the 90028 ZIP and surrounding Hollywood corridors, from the Spanish Colonial Revival courts near Franklin Avenue to the 1950s dingbat blocks along Cahuenga Boulevard. Our Heat Pump & Mini Split crew knows the neighborhood’s housing stock inside out — the plaster walls, the missing attics, the floor furnaces that haven’t seen service since the Reagan administration. If your mini split died during last October’s Santa Ana spike or you’re finally done with a wall heater that roars but doesn’t warm, call us at (855) 467-1888. Jason Trent supervises every project personally.
Why Stonegate Heating & Air California Is Hollywood’s Preferred Heat Pump & Mini Split Company
We’ve spent 16 years building a 4.7-star reputation across nearly 500 verified reviews, and a growing share of those calls now come from Hollywood landlords and homeowners who’ve cycled through contractors who didn’t understand the building stock. One property manager on Highland Avenue told us she’d fired three companies before finding us — each one walked into her 1920s courtyard building, saw the plaster-and-lathe walls, and tried to sell her ductwork that couldn’t physically fit.
Jason Trent doesn’t delegate site assessment to a sales rep. As Field Supervisor, he’s on the job, measuring clearances, tracing existing chases, and designing around constraints that only exist in pre-WWII construction. That matters in Hollywood, where “standard” HVAC practice fails because the buildings weren’t built to any standard we’d recognize today.
Our response time to Hollywood averages same-day or next-morning for non-emergency calls, and we carry factory-authorized parts for Daikin, Bryant, and Carrier systems to avoid the week-long parts chase that strands other contractors. We’ve done enough Hollywood retrofits to know which exterior walls can take a line-set sleeve, which floor furnaces are too far gone to coexist with new equipment, and when a multi-zone mini split is the only logical path forward.
Our Heat Pump & Mini Split Services in Hollywood
Mini Split Install
This is our most common Hollywood request, and for clear reason. In Hollywood’s 90028 ZIP, over 70% of pre-war apartment buildings were built with zero ductwork, making ductless mini-split retrofits the dominant HVAC job type rather than the exception. Unlike newer surrounding communities where forced-air replacements are routine, Hollywood technicians must routinely design systems around plaster-and-lathe walls, zero attic clearance, and zero existing air distribution infrastructure. We size each zone individually, route line sets through exterior chases or existing wall cavities where possible, and mount indoor heads at heights that work with original window placements and crown molding. Most Hollywood mini split installs run $3,500–$7,500 depending on zone count and electrical upgrades needed.
Ductless System Design
A ductless system in Hollywood isn’t just “no ducts” — it’s a deliberate response to buildings that actively resist conventional HVAC. We design for buildings where the mechanical room is a closet under the stairs, where electrical panels are original 60-amp service, and where every hole in a plaster wall creates a repair cascade. Our ductless layouts preserve architectural integrity while delivering heating and cooling to spaces that have never had either. We’ve installed systems in Franklin Avenue bungalows where the only viable path was up the exterior wall and through a soffit, and in Highland Avenue four-plexes where each unit needed its own compressor because the landlord couldn’t run shared lines across property lines.
Multi-Zone System
Hollywood’s multi-family housing practically demands multi-zone mini splits. A single outdoor compressor can serve two to eight indoor heads, letting each tenant control their own temperature without shared ductwork or landlord disputes over usage. We configure Daikin and Bryant multi-zone systems for Hollywood properties regularly, sizing outdoor units to handle the combined load while allowing individual head shutoff when rooms are vacant. This is particularly valuable in courtyard apartment buildings where each unit faces a different solar exposure — the south-facing unit needs cooling in February while the north-facing neighbor is still running heat.
Heat Pump Repair
Hollywood’s heat pump repair calls spike hard each October and November when Santa Ana winds blast through the Cahuenga Pass. Temperatures jump into the high 90s or low 100s, and mini splits that sat idle for months suddenly face full cooling load. We see compressor lockouts, tripped breakers, and refrigerant leaks from thermal expansion stress. Our repair calls for heat pumps and mini splits in Hollywood run $150–$650 depending on whether we’re clearing a fault code, replacing a failed capacitor, or recovering and recharging refrigerant. Jason Trent carries common failure parts on his truck for Daikin, Carrier, and Bryant systems to complete most repairs in a single visit.
Heat Pump Installation
For Hollywood properties with some existing infrastructure — rare, but they exist in 1950s–1960s dingbat apartments along corridors like Cahuenga and Highland — a conventional heat pump can replace an aging wall heater and add cooling where none existed. These installs require careful load calculation because the building envelope is leaky and original insulation is minimal. We size conservatively, specify equipment with good low-ambient heating performance for Hollywood’s occasional 40°F winter nights, and ensure electrical service can handle the compressor startup load. When the building can’t accommodate ducts, we pivot to mini split without upsell pressure — just an honest assessment of what will actually work.
Mini Split Repair
Mini split repair in Hollywood carries unique challenges. Plaster-and-lathe walls crumble when technicians attempt to fish new refrigerant lines, requiring careful, non-contact routing through existing chases or exterior sleeves. Original 1930s–1940s gravity floor furnaces still in operation block logical placement of indoor mini-split heads, forcing complete ductless system redesigns just to restore basic heat. We troubleshoot the full system — compressor, line sets, indoor heads, condensate drainage, and control wiring — rather than guessing at the symptom. Our tune-up service for mini splits runs $80–$200 and includes coil cleaning, refrigerant pressure check, and drain line clearing, which prevents the mold and algae buildup that’s common in Hollywood’s mild, humid shoulder seasons.

Trusted Brands We Service in Hollywood
We’re factory-trained or field-experienced on nine major brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — which means whatever equipment is already in your Hollywood building, we don’t start with “we don’t service that.” For mini splits specifically, we specify Daikin and Bryant most often in Hollywood multi-zone applications because their inverter-driven compressors handle the partial-load conditions of mild California weather efficiently, and their indoor head profiles fit well in rooms with 8-foot plaster ceilings and limited wall space. We stock common Daikin and Bryant control boards, sensors, and refrigerant fittings locally to avoid the supply-chain delays that turn a two-hour repair into a two-week ordeal. If you have a Carrier system already, we service those too — no brand abandonment, no forced upgrade.
Common Heat Pump & Mini Split Problems We See in Hollywood Homes
- Santa Ana wind compressor failures. During Santa Ana winds in October–November, neglected mini splits fail from sudden spike loading after months of disuse, leading to compressor lockout or tripped breakers. The mild marine-influenced summers that dominate most of the year cause many residents and landlords to neglect cooling maintenance, so systems fail precisely when the rare but severe heat events arrive.
- Plaster wall damage during line-set routing. Plaster-and-lathe walls crumble when technicians attempt to fish new refrigerant lines, requiring careful, non-contact routing through existing chases or exterior sleeves. We’ve seen other contractors punch holes that cost more to repair than the HVAC work itself.
- Gravity floor furnace obstruction. On service calls in older Hollywood apartment buildings, technicians regularly find original 1930s–1940s gravity floor furnaces still in operation — units that haven’t been serviced in decades and are often wedged beneath hardwood floors with no accessible flue path, leaving no straightforward upgrade route and forcing a full ductless redesign just to restore basic heat.
- Condensate drain clogging from marine humidity. Hollywood’s proximity to the coast means higher humidity than inland valleys, and mini split condensate lines without proper pitch or regular cleaning back up into wall cavities. We’ve opened plaster walls to find years of accumulated algae and mold — preventable with annual tune-ups.
Pricing for Heat Pump & Mini Split in Hollywood, CA
Here’s what we actually charge for heat pump and mini split work in Hollywood. These ranges reflect real jobs we’ve completed in the 90028 ZIP and nearby corridors. Every project starts with a free, no-obligation estimate — Jason Trent visits, measures, and specifies before any work begins.
| Service | Hollywood Price Range |
|---|---|
| AC Repair (Mini Split) | $150–$650 |
| AC Installation (Mini Split) | $3,500–$7,500 |
| Tune-Up (Mini Split) | $80–$200 |
What moves you within these ranges? Zone count is the biggest factor — a single-head mini split for a studio apartment sits at the lower end, while a four-zone multi-split for a courtyard building approaches the top. Electrical service upgrades, if your building still runs 60-amp panels, add cost. Exterior line-set routing through stucco versus through interior chases affects labor hours. And the condition of existing equipment matters — removing a dead gravity floor furnace and sealing the opening takes time that a simple wall-mount replacement doesn’t.

We Also Serve Cities Near Hollywood
Our heat pump and mini split crews work throughout the Hollywood-adjacent corridor, including Universal City, West Hollywood, Koreatown, and Echo Park. Each shares some of Hollywood’s housing-stock challenges — the 1920s courtyard buildings extend into Koreatown, the dingbat apartments line streets in Echo Park — but Hollywood’s concentration of zero-ductwork pre-war construction remains the most complex retrofit environment we serve. If you’re in one of these neighboring cities and your building dates to the same era, the same expertise applies.

FAQs — Heat Pump & Mini Split in Hollywood
Yes — in fact, most of our Hollywood mini split installs happen in buildings with no attic at all. We route line sets through exterior wall chases, along rooflines with proper concealment, or through existing plumbing and electrical cavities. Just last fall, our crew rewired a 1930s Spanish Colonial Revival bungalow off Franklin Avenue where the original wall heater had rusted through. We installed a Daikin multi-zone mini split to service three bedrooms and the living room, running line sets through an exterior chase to avoid cutting into plaster-and-lathe walls. Call (855) 467-1888 and we’ll survey your specific routing options — estimates are free.
Yes, and we design specifically to avoid damaging them. Mini split indoor heads mount to the wall surface, requiring only a single 3-inch penetration for the line set, condensate drain, and control wire. We avoid fishing lines through plaster cavities that will crumble and crack. For Hollywood’s Spanish Colonial Revival and Craftsman buildings, exterior routing or existing chase utilization preserves original wall finishes. We’ve completed dozens of these installs without a single plaster repair callback. Jason Trent measures every penetration point during the estimate to confirm the path.
Santa Ana winds can trigger sudden compressor failures in mini splits that haven’t run hard since the previous summer. The Cahuenga Pass funnels these events directly into Hollywood, with temperatures spiking 30–40°F above seasonal norms in October and November. Systems that sat idle during mild weather get slammed with full load, revealing refrigerant leaks, weak capacitors, and dirty coils that weren’t apparent in gentle operation. We recommend a $80–$200 tune-up in September before Santa Ana season, or at minimum a filter and coil inspection. If your mini split locked out during the last wind event, call (855) 467-1888 — we carry compressor start kits and refrigerant to restore cooling same-day.
Usually no — and for safety reasons, we don’t recommend it. Original 1930s–1940s gravity floor furnaces in Hollywood often have deteriorated heat exchangers, blocked flues, or no accessible service path, creating carbon monoxide risks that outweigh any perceived savings. When we find these units still running, we recommend complete removal and replacement with a ductless mini split that provides both heating and cooling. The floor opening gets properly sealed and insulated. This is a full redesign, not an add-on, but it eliminates a hazardous appliance while giving you year-round climate control. We’ll assess your specific furnace condition during the free estimate and give you an honest read on whether it can safely remain.
We specify Daikin and Bryant most often for Hollywood multi-zone applications. Both offer inverter-driven compressors that modulate efficiently at partial load — critical in a climate where full capacity is rarely needed. Daikin’s VRV and VRV Life series handle up to eight zones from one outdoor unit, fitting well in courtyard buildings with limited ground or roof space for multiple compressors. Bryant’s Evolution multi-zone systems offer similar flexibility with slightly different control interfaces that some property managers prefer for tenant training. We don’t push one over the other; we match the brand to your building’s electrical service, zone count, and your preference for wall-mounted versus ceiling-cassette indoor heads. Carrier systems are also excellent if you have existing Carrier equipment and want consistent controls across the property.
